Public anxiety is building over severe pollution levels in Delhi and the health toll of air pollution in India as a whole. At a recent hearing of the long-standing case on air pollution, the Ministry... India is considering making a jump from Bharat IV directly to Bharat VI emissions standards. There are some concerns about cost. One effective way to answer them would be to establish a national HDV...

In many regions of the world, older, high-emitting vehicles account for a small percentage of the overall vehicle fleet but a disproportionately large share of total emissions. These vehicles may be...

Heavy-duty vehicles built and certified in conformity to Euro IV and V emissions standards frequently do not achieve the real-world NOx emissions expected under those standards. Now data is becoming...

Producing first generation biofuels requires feedstock. When that feedstock comes from supplies of food crops (wheat, maize, rapeseed, soy etc.) then using it for biofuel production means it cannot... The idea of ‘low-ILUC risk’ biofuels has been around for a while, and a recent paper identifies the type of regional policies that could allow ILUC to be avoided. But are recent proposals to add the...

In contrast to passenger cars, data on HDV fuel efficiency are not readily available. That is the primary motivation for this literature review, which provides a summary of recent data on real-world...

After we published our new test cycle conversion factors, a question came up: which of the test cycles is the most demanding, in terms of its impacts on fuel efficiency or CO2 emissions, and how much... Even though it’s a simple enough question, it has no simple answer, since the new conversion factors vary with vehicle efficiency and are different for gasoline and diesel engines. However, in our...

An increase in the excise duty in India has caused car prices there to rise since the beginning of this year. India's excise duty is based on vehicle size — specifically, length and engine... India’s increase in the excise duty and absence of LCV fuel-efficiency standards may lead some manufacturers to categorize some models as LCVs to avoid the fuel-efficiency standards.

The International Council on Clean Transportation (ICCT) is a non-profit organization whose mission is to improve public health and mitigate climate change through research designed to bring cleaner...

In Europe by now we have gained considerable experience with setting CO2 standards for light-duty vehicles: First, in 2009 a target of 130 g/km for 2015 was adopted, then 2014 the target of 95 g/km... The IKA institute just released a study on technology potential and cost for 2025/2030 CO2 targets in the EU—an opportune moment to look back at all the previous such studies and see how accurate...

If you paid attention to the press coming out of the Detroit Auto Show last week, you’d have the strong impression that low gasoline prices are making it difficult for automakers to comply with fuel... Sergio Marchionne, among others, is trying to get folks riled up about rolling back the 54.5 mpg standard for new 2025 automobiles. Let’s take a little closer look at the supposed problem.
